Hey April! I can't wait to see your wedding! To add on to the advice you've already received, you can also go to the "My Wedding" tab and scroll down to "Married at last". Under there is the option to share your wedding. And here's a link to take you directly to it.
Just to add on to what Jessica was saying - if you are on the computer then after clicking "My Wedding" and then "contests" you have to click "request entries" and it will take you to a page where you can click "Share your Real Wedding" once your wedding has come and passed.
(I'm only mentioning this because if you are like me I was lost after hitting "contests" and not having a submit wedding option on that page.)
